Menegazzia subsimilis
Key Details
| Taxonomic Groups: | Fungus or lichen > lichen > Lichen |
| Red List Status: | Near Threatened (Not Relevant) [NT(nr)] |
| D5 Status: | Included in the baseline Red List Index for England (Wilkins, Wilson & Brown, 2022) |
| Section 41 Status: | (not listed) |
| Taxa Included Synonym: | (none) |
| UKSI Recommended Name: | Menegazzia subsimilis |
| UKSI Recommended Authority: | (H. Magn.) R. Sant. |
| UKSI Recommended Qualifier: | (none specified) |
| Red List Citation: | Woods & Coppins, 2012 |
| Notes on taxonomy/listing: | (none) |
Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | One extant site in England, threats present. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | A very small population at one known extant site. Known but unquantified threats from nitrogen deposition, invasive rhododendron, and lack of grazing some of which will require targeted action (Douglas, 2021). |
| Question 3: | At a landscape scale, would the species benefit from untargeted habitat management to increase habitat mosaics, structural diversity, or particular successional stages? |
| Response: | Yes |
| Justification: | Part of a large group of species threatened by under grazing of old growth woodlands. Likely to benefit from diverse woodland structure, especially sheltered glades. |
Species Assessment
| Current step on the Species Recovery Curve (SRC): | 4. Autecology and pressures understood |
| Recovery potential/expectation: | Medium-high |
| National Monitoring Resource: | Opportunistic - insufficient |
| Species Comments: | Only known in England from one site in Cumbria, Stanley Ghyll. |
Key Actions
Key Action 1
Proposed Action: Assess current status of Menegazzia subsimilis at Stanley Ghyll, identify threats and actions to address these.
Action targets: 5. Remedial action identified
Action type: Status survey/review
Duration: 1 year
Scale of Implementation: 1 site
High priority sites: Stanley Ghyll, Cumbria
Comments: Threats known to exist but current status of the species, the issues directly impacting it and the actions required to address these not known.
Key Action 2
Proposed Action: Undertake remedial action identified in Action 1. Likely to require Rhododendron ponticum control on steep ground and grazing management.
Action targets: 6. Recovery solutions trialled
Action type: Habitat management
Duration: 6-10 years
Scale of Implementation: 1 site
High priority sites: Stanley Ghyll, Cumbria
